Sunshine and Shadows in New Mexico's Past has one main goal: to reveal the sharp contrasts in New Mexico history. As with all states, New Mexico has had its share of admirable as well as deplorable moments, neither of which should be ignored or exaggerated at the other's expense. New Mexico's true character can only be understood and appreciated by acknowledging its varied history, blemishes and all.

The first of three volumes, Sunshine and Shadows in New Mexico's Past: The Spanish Colonial and Mexican Periods represents the New Mexico Historical Society's humble gift to New Mexico as the state celebrates its centennial year of statehood in 2012.
